Structure of Connective Tissue (C.T)
- Consists of three main components: cells, matrix, and fibers
- Types of C.T: soft, rubber, solid, and fluid
Connective Tissue Proper (C.T Proper)
- Includes cartilage, bone, and blood
- Cartilage: has a matrix of C.T proper
- Matrix of C.T proper: amorphous ground substance, transparent and gel-like material
Pericytes
- Found around blood vessels
- Can differentiate into fibroblasts and smooth muscles during wound healing
- Functions: surround blood vessels, can differentiate into other cells
Endothelial Cells
- Found in: lining all blood vessels and the endocardium of the heart
- Characteristics: thin, flat cells with flat nuclei
- Functions:
- Divide to produce new endothelial cells to repair injured blood vessels
- Produce anti-thrombotic factors, which prevent platelet aggregation
Fibroblasts
- Origin: pericytes
- Found in: most common type, found nearly in all types of C.T
- Staining: silver stain, appears brown to black
- Functions:
- Form the stroma of organs, e.g. bone marrow and glands, e.g. liver
